Abstract

The invention belongs to the field of ocean structure physical testing simulation and particularly relates to a testing device for simulating an organic coating washout environment. The testing device for simulating the organic coating washout environment is used for simulating a corrosion behavior of an organic coating in a washout environment under a certain condition. The testing device for simulating the organic coating washout environment comprises a power portion and a washout portion; the power portion continuously provides power for circulation flow of a washout medium fluid in the washout portion; the washout portion achieves a washout test of samples. The testing device for simulating the organic coating washout environment is particularly designed for the organic coating, an arc-shaped sample plate and a jet flow sample panel can effectively protect positions with large sampling curvature being not directly washed by the washout fluid, a piston system drives a solid-liquid two-phase fluid not to pass a driving pump, and accordingly abrasion of the driving pump is avoided, a horizontal and vertical section organic coating pipe wall washout environment can be simulated, and the jetting angle can be accurately adjusted outside a jet flow chamber.

Description

technical field [0001] The invention belongs to the field of physical test simulation of marine structures, and in particular relates to a test device for simulating an erosion environment of an organic coating, which is used in a laboratory to simulate the corrosion behavior of an organic coating in an erosion environment under certain conditions. Background technique [0002] Erosion is a phenomenon in which the surface is damaged due to relative motion between the metal surface and the fluid. The microscopic failure includes wear, corrosion and their interaction. In industries such as petroleum, chemical industry, shipbuilding, electric power and transportation, there are many metal flow-passing parts in contact with corrosive fluids. These flow-passing parts often fail due to the erosion of fluids, resulting in property losses and even casualties. . Spraying organic coatings on metal surfaces is a simple and effective way to slow down corrosion. [0003] At present, mo...
